BMI calculator

A quick weight-for-height check, with its limits spelled out.

ft
in
lb

Enter your height and weight.

How it works

  • Weight in kilograms divided by height in meters, squared.
  • Categories follow the World Health Organization ranges.

Keep in mind

BMI can't tell muscle from fat, so lifters often read as “overweight”. Use the body fat calculator for a better picture.
